IMPROVEMENT IN THlLL-COUPLINGS.

Specification forming part of Letters Patent No. 216,458, dated June 10,1879; application filed April 21, 1879.

To all whom it may concern:

Be it known that I, MORRIS H. RIssER, of Homerville, in the county ofMadison and State of Ohio, have invented a new and valuable ImprovementiuSpring Coupling-Pins for'lhills and Poles; and I do hereby declarethat the following is a full, clear, and exact description of theconstruction and operation of the same, reference being had to theannexed drawings, making a part of this specification, and to theletters and figures 0f reference marked thereon.

Figure 1 of the drawings is a representation of a perspective view ofthis invention. Fig. 2 is a partial sectional view of the pin.

This invention has relation to means for coupling the thills or poles ofwagons or carriages; and it consists in the construction and novelarrangement of parts, as hereinafter shown and described.

In the accompanying drawings, the letter A designates the shackle, and Bthe end of the thill or pole gear. 0 represents the coupling-pin, madewith a broad bearing-head, a, from which extends a flat spring portion,b, in loop form, around to the point 0 of the pin, with which it engagesby means of a perforation, 01, made in the thickened or re-enforeed ende of the spring.

The point 0 is small in diameter to the body of the pin, and formstherewith a shoulder, 71, by which means the body of the said pin thatreceivesthe strain may be made very strong, and, the point a being ofcomparatively small diameter, the hole d in the free end of theloopspring may be made so small as not to weaken it unduly. Thisperforated end of the spring passes over the point of the pin, which isbeveled, and bears byits elastic force against the side of theshackle-arm, thereby taking up all slack and preventing the pin fromworking or rattling in its bearings, and effectually securing it in itsplace.

This pin is introduced into its place by disengaging the spring from itspoint, and passin g the pin through the cockeyes and the thill or polebearing and the spring portion underneath the same, and then engagingthe spring end with the point of the pin. This is readily and quicklydone without wrench or tool,and saves much time, especiallyin changingfrom thills to pole, as the removal of the pin from its bearings, isefi'ected with equal facility.

As the spring constantly presses against the cockeye it keeps the pintight, and there can be but little wear, especially as the spring iscast-steel and the coekeye usually of iron.

The entire coupling or shackle and pin is made in one piece ofuntempered east-steel.

I am aware that a spring-fastening, in connection with the thill-eve.and axle-clip eyes, are not broadly new, and I do not claim suchinvention.

What I claim as new, and desire to secure by Letters Patent, is-

As a new article of manufacture, a pivot fastening for thill or polecouplings, consisting of the pin 0, having the rahbeted point a at oneend, and the enlarged spring I), extending in loop form from the head ato point e, and having are-enforced end, 0, provided with a perforationdesigned to spring over the point (1, the whole made in one piece ofuntempered cast-steel, as specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

MORRIS HENRY RISSER.
